coverStonehenge, by Robin Heath, from Walker & Co., ISBN 0802713858. Originally constructed before 3000 BC and developed over the next 1,500 years, Stonehenge is a Stone Age cathedral, relic of a once wealthy and learned tribal community and the centerpiece of an impressively large culture of stone circles. This elegant volume, illustrated with engravings from rare books and drawings by the author, explains who built Stonehenge and why, how it was used to predict eclipses, why some of its stones were brought from Wales, and many other intriguing details.
